1.3 BRIM-WT1 OVERVIEW
The BRIM-WT1 is an optional feature for the MicroMMAC. It allows
remote connectivity of the MicroMMAC using WAN services such as T1,
Fractional T1, and Digital Data System (DDS). The BRIM-WT1 extends
the functionality of the MicroMMAC to include remote bridging and
routing capability. With the BRIM-WT1, the MicroMMAC is a remote
office workgroup hub providing up to 130 LAN ports of connectivity.
1.4 BRIM-WT1 FEATURES
WAN Connectivity
The BRIM-WT1 is equipped with a Synchronous (SYNC) serial port and
a T1/Fractional-T1 (T1/FT1) port.
The SYNC port provides a synchronous serial connection to external
WAN equipment (e.g., a T1 multiplexer or DDS). This port supports the
following interfaces:
•
•
•
•
•
RS232 (9.6 Kbps - 19.2 Kbps)
RS422/RS449 (9.6 Kbps - 2.048 Mbps)
RS530 (9.6 Kbps - 2.048 Mbps)
X.21 (9.6 Kbps - 2.048 Mbps)
V.35 (9.6 Kbps - 2.048 Mbps)
Page 2
BRIM-WT1 USER’S GUIDE
BRIM-WT1 SPECIFICATIONS
The T1/FT1 port provides a DSX-1 interface that includes a built in
Channel Service Unit/Digital Service Unit (CSU/DSU) for direct
connection to a T1 line. This port supports both Full T1 or Fractional T1
using 56 or 64 Kbps timeslots.
WAN Protocols
The BRIM-WT1 supports the following WAN protocols:
•
•
Point to Point Protocol (LCP and BNCP), as defined by RFC1331
Frame Relay (LMI), as defined by RFC1294
MIB Support
For additional information on how to extract and compile individual
MIBs, contact Cabletron Systems Technical Support (see Getting Help).
The MicroMMAC (with the BRIM-WT1 installed) supports the following
Wide Area Network IETF MIBs:
•
•
•
•
•
RFC1406 (DS1 Connection Management)
RFC1317 (RS232 Like Connection Management)
RFC1471 draft (PPP Link)
RFC1474 draft (PPP Bridge)
RFC1315 (Frame Relay)
LANVIEW Diagnostic LEDs
Cabletron provides a visual diagnostic and monitoring system, called
LANVIEW, with the BRIM-WT1. LANVIEW LEDs help you quickly
identify Bridge and Link status.

Setting WAN Physical Configuration Screen Fields
To set a WAN Physical Configuration screen field:

2. Press the Return key to toggle the selections.
3. When the desired selection appears, use the arrow keys to highlight the
SAVE command.
4. Press the Return key or press F6. The message “Save Done!” appears
and the changes are saved to memory.
Setting the T1 Timeslot Configuration Table
The T1 Timeslot Configuration Table allows you to configure how your
MicroMMAC utilizes the T1 line. The configuration table consists of 24
Timeslots, which appear as 01-08, 09-16, and 17-24. You must assign
each Timeslot an Interface number (03-26, or 00 if the Timeslot is not
used). When you lease an entire T1 line, you can use all 24 Timeslots (the
full T1 bandwidth). If you lease only a fraction of the T1, the Telco carrier
will tell you which Timeslots to use.
You can utilize Timeslots any way you choose. For example, if your
MicroMMAC has access to a full T1 (24 Timeslots), and you want to
communicate with two other MicroMMACs, your configuration could
look like figure 3-2.

Figure 3-3 shows a sample configuration for three MicroMMACs. Of the
24 Timeslots, MicroMMAC#1 uses 16 to communicate with
MicroMMAC#2 and the remaining 8 to communicate with
MicroMMAC#3. This configuration can vary tremendously, depending on
how the Telco carrier maps out the T1 Timeslots. Your Telco carrier will
tell you which Timeslots are active.

MicroMMAC#1 is using the full T1, so all the Timeslots must have an
Interface assignment. MicroMMAC#2 and MicroMMAC#3 only use a
fraction of the T1, but the quantity of Timeslots must match those of
MicroMMAC#1. Unused Timeslots receive an Interface number of 00.
Note: The Interface numbers of MicroMMAC#1 and MicroMMAC#3 do
not have to match. Only the quantity of Timeslots must match (the Telco
carrier will assign the timeslots).
To set the Timeslot Configuration Table:

PT#
Displays the Bridge Port that the BRIM-WT1 Local Management
automatically assigns to an Interface. If the active protocol for this
interface is PPP, Local Management assigns only one WAN bridge port. If
the active protocol is Frame Relay, Local Management may assign up to
31 WAN bridge ports.
Note: The MicroMMAC has 32 available bridge ports. Ethernet is the
first bridge port. The remaining 31 bridge ports are available for WAN
applications.
You can assign the 31 WAN bridge ports to the 24 interfaces in the
configuration that suits your needs. For example, you can assign all 31
WAN bridge ports to one interface. In this example, the remaining 23
interfaces would not have WAN bridge ports available.
The quantity of bridge ports for a Frame Relay network is determined by
the quantity of DLCIs (Data Link Connection Identifiers) assigned to that
Interface. This is determined either manually or by the LMI (Local
Management Interface).
IF#
Displays the Interface that is associated with the bridge port.
DLCI

CHAPTER 4
USING THE LANVIEW LEDS
This chapter describes how to use the LANVIEW LEDs to monitor BRIM
status and diagnose BRIM problems.

4.1 BRIM-WT1 LEDS
The following LEDs indicate the status of the BRIM-WT1.
STB (Standby)
•
On -All WAN bridge ports are in the non-forwarding state. Possible
causes of this condition are: redundancy detected by Spanning Tree,
data link layer down, physical layer down, or port disabled.
Blinking - Some WAN bridge ports are in the forwarding state and
some WAN bridge ports are in the non-forwarding state.
•
•
Off - All WAN bridge ports are in the forwarding state.
SYN (Synchronous)
•
•
On - SYNC port is active.
Off - T1/FT1 port is active.

4.2 T1/FT1 PORT LEDS
The following LEDs indicate the status of the T1/FT1 port.
LOS (Loss of Signal)
•
On - Indicates a loss of link at the T1/FT1 port. This condition
occurs when the T1/FT1 port receives 192 consecutive 0’s, this
should not happen under normal conditions. Check the T1 port
cable.
•
Off - Signal OK.
TST (Test)
•
•
On - Indicates that the T1/FT1 port is in the test mode.
Off - Indicates that the T1/FT1 port is in the non-test mode.
YEL (Yellow Alarm)
•
On - Indicates that the remote bridge has lost T1 Frame
synchronization. Check the remote bridge, T1 port cable, or T1
Frame Type setting.
•
Off - Synchronization OK.
RED (Red Alarm)
•
On - Indicates that the bridge has lost T1 Frame synchronization
with the remote bridge. Check the remote bridge, T1 port cable, or
T1 Frame Type setting.
•
Off - Synchronization OK.

SYNC PORT LEDS
4.3 SYNC PORT LEDS
The following LEDs indicate the status of the SYNC port.
DSR (Data Set Ready)
•
On - Indicates that the DCE is ready to operate, or that the Force
DSR True field (refer to the WAN Physical Configuration screen) is
set to YES (On).
•
Off - A valid DSR is not being received from the DCE. Check the
cabling or check if the DCE is powered on.
CTS (Clear to Send)
•
On - Indicates that the DCE is ready to receive data from the
BRIM-WT1, or that the Force CTS True field (refer to the WAN
Physical Configuration screen) is set to YES (On).
•
Off - A valid CTS is not being received from the DCE. Check the
cabling or check if the DCE is powered on.
LNK (Link)
•
•
On - Indicates that the BRIM-WT1 is receiving a valid clock from
the DCE.
Off - Indicates that the BRIM-WT1 is not receiving a valid clock
from the DCE. Check the cabling, check that the DCE is powered
on, or check that the clock source is set properly in the DCE.
TST (Test)
•
•
On - Indicates that the SYNC port is in test mode.
Off - Indicates that the SYNC port is in non-test mode.
